How the energy of separation in an atom or molecule is related to wavelength of Laser emission?
Answers
Answer:
This happens every time an electron drops from a higher energy state, , to a lower energy state, , in an atom or ion as occurs in a fluorescent light. ... The difference in energy levels across which an excited electron drops determines the wavelength of the emitted light.
Answer:
Laser emission via a one-photon excitation process (He et al. 1994) or a two-photon excitation process (Zhao et al. 1995, He et al. 1996) from dye doped solid matrices has been reported. These composite glasses exhibit excellent slope efficiencies (up to 39%). The success of a solid-state dye laser depends mainly on its photostability and mechanical properties. Sol–gel derived composite glasses offer better photostability, optical quality, and mechanical stability as compared to other organic matrices. Solid-state dye lasers could be useful for applications where only low laser output is required, e.g., photodynamic therapy (PDT), medical diagnostics of tissues using laser-induced fluorescence (LIF), and photodynamic purification of blood from viruses.
